Application' filed November' 23;

.lie itknown that Q, lnMiin R. Porn, a citizen ot the United States, residing' at Ham# ilton, in the county o'if Essex and Common wealth ot iiassachusetts.vv have invented certain improvements ini l?asteninglnserting lilachinemoif which the toliowinef` description. in connection with the accompanying drawing, a specification', like reference characters on the fili'awingrs indicating:r like parts in the several figures,

Myinvention relates to n'iachines ttor inserting' nails and similar tasteningg's, and especially to those tor nailingv the licei-seats oi" shoes. ln the application in my name bearing the Serial Number (503,576, tiled in the United States Patent @tiice November 2i. i922, is disclosed an apparatus in which close proximity to the land-crease oi:l` the points oi' insertion of' heel-seat-nails is assured by holding' each nail in a movable sertioni which is 'forced into nailing'` position by the introduction o'ii the shoe to be operated upon;l Vith each oi these movable seetions v(1o-operates areciprocatory driver, completing, with the holding' section, a nailing mechanisni, each driver being; movable inde-- pendentlv of the section and brought to the .nail-inserting relation by its contact with the correspoudinev holdingsection. The object ot the present ii'ivention is to improve such al structure, particularl'y with reference to the positioning: oi the holdinn' sections by (he work and the manner of actuation of' the dri vers.

Tn the attainment ot' thisfobject, a leature ot the invention consists of a movable supp'ort,as aiy jack for a shoe, toward and Yfrom which a 'tastennninserting mechanism is niovable, together with means, as a spring, Yfor moving the inserting mechanism toward the support, and novel means controlled by the support for opposing' the action of the moving;v means. The thus controlled means is 'shoivnfas consistingiol a Weighnnormally opposing the action oit lthe spring', but hav ingl its-eiliect thereonovcrcome as the Worl'- support is .moved into nailing; position, so that the inserting' mechanism is at this time carried into engagement Wit-h the supported shoe. Byr this combination, rubbing effect upon the Worlr by itsv movement along the contacting inserting mechanisms yis avoided7 1323.' Serial No." 676,6482

the latter travelingi directly against the shoeupper when itv is at rest.

A, further 't'eature oit the invention involv's the holding. of the mechanisms against separation from the Work` during,Y the iiiseriing operation." This is eiiiec-ted by means acting in the moven'ient ot a member which actnates the inserting' mechanisms, and vfhichprevents movement oi. said mechanisms. lviore speciiieally,a pressure member, movable to depress the drivers-which insert the nails, also operates a retaining member for each section ot' the inserting` mechanism, these retaining' members being' preferably yieldable. 'llhus,the sections are held firmly in their inserting' positions during the driving;Y ci the nails.

Another feature oi" the invention concerns the actuation ot the inserting .members off the independently movable mechanisms, this being' accomplished by an actuating' member movable into and out of (5o-operation with such'insertingziiiieohanisms. rEhere are herein illnstrated carriers arranged to recipro cate in the sectionsof the inserting;v mechanisms, and eachA having'` a driver mounted upon it, anda reeiproeatory pressure-head movable independently oi the carriers' and acting upon them (o operate the drivers. The independence ot movement of the pressure-heini, upon theone hand,` and the sections with theircarriers and drivers, upon the other, produtes acapacity` ot the sections ior ready adjustment to the work, to give the propel" insertion oi the tasteninle's and a treedom 'from strain upon the drivers ivhen these are actuated.

A particular embodiment oi.i the invention is illustratedv in the accompanying'. drawings,

The generalcharacteristics-of the form oi' ter-'poi"ri on ot the upper.

machine which l hare chosen to disclose herein may be substantially those ot the air para-tus et' Patent No. 41426585, Pope, February 24, i891. This includes a trame l0 having' separated portionsQ between which extends a horizontal die-block 127 this fur nishine' an abut-ment against the under side ol" which is pressed the heel-seat of' a shoe i which is to be nailed. At the area of contact olE the heel-scat with the die-block is shown a recess 14, 'formed at tl e bottom ot' the die-block, this recess serving as a mold, which, as a result ot the pressure applied during;` the nailing' operatioin imparts to the heel-seat the contour ot the concave end ot the heel which is to be later attached. The shoe iii is carried by a jack 1G mounted to more in ways 1T extendingr 'from front' to rear ot the frame, the ways being' at the top ot a cross-head '18 arranged to reciprocate vertically in the 'trame-E Vith the cross-heed in its lowered position and the jack drawn out, the shoe to be operated upon may be placed upon said jack, and then pushed in along the ways 1T until it is beneath the dieblocli. In this position, the machine may be operated to apply pressure to the. heel-seat to torni it and hold it 'tor the insertion ot' the nails. Arranged to reciprocate in the ilrame, at each extremity et the die-block t,y are vertical side rods 19 carrying at theirI upper extremities connecting` yoke or top girt 20.

The body 22 oft the die-block may be termed in sections, to facilitate the assembling' with it of the elements which it guides, and is provided with a series ot vertical slots 2l; extending' outwardly from the recess 11i, these slots having' the relation best illus trnted in Fig'. 4 ot the drawings. 'ln the slots more the body-sections 2S o'tl nailvinsorting mechanisms, a section slidingin each slot and heinel supporterflilw said portions in) and au end portion 3th which overhang' and rest upon the upper surlace o lthe die-block. Upward displacement may be prevented by plates rl attached to the bottom oit tht` sew tions. Each sect-ion has in its inner1 lower portion a holding passage 363, which is preterably inclined downwardly and inwardly. so that the tastenings which these passages contain will be drive-n toward the interior ot the shoe7 and not parallel to or in the direction oit the counter-portion. this arrruug'emcnt7 the lieel-seatsecuriug 'tastenines may be inserted close to the edge ot the ontschn to produce a tight rand-crease without r'lz'tngger ot their emerging through the coun- Nails N are delirered to the holdinc' passages through. communicating passages extending;` 'trom the 'former in a nearlyv vertical directionn and to which, at the top ot' each section 28, ,is cf'vnnected a ilegible supply-tube 36. The tubes are joined to the discharge device of a suitable distributing mechanism 3S, which maybe similar to that which is the subject olt ilatent No. (SSS/ITT, McFeely, December l1, i900. The tleaibility ot' the tribes 36 permits movement oi the sections 28 along the slots in the die-block, without interfering with the delivery ot nails. Alined with each passage 232 is an opening 40, shown as rectangular in transverse section. lin this opeuincY is located a carrier-bar 4t2 arranged to reciprocate longitrulinally and having secured to its lower c:.\'tremity a driver 441,-. 'ihis dri ver operates in the alined :tissage 32, contacting'7 in the movement ot' the car ricr-bar, with a nail in the passage, to drive it into the heel-scat of a shoe held on the jacli beneath the dic-block. vEach bar and driver is normally raiserh so that the lower end ot the latter is above the nail-deliver),v passage 31h b v a springl tti located within the opening et() and situated bctwien the bottom ot the bar and a depression in the section QS. ilach d river-bar t2 is `guided between walls wth which rise above and extend alone' the opposite sides ot the slots Q4. Each section is forced inwardly by a sprintY 5t) held within a bore. in the section and abutting at its outer end against. a screw-pineY threaded through the all of the diebiock at the end ot the corresponding slot. The extent ot inward movement oic each section is raged by a projection 5G adjustably fixed to the under side ot the section by a slot-aml-screw connection The inner end ot the projection is so 'formed as to generally correspond to the contour of the counter-portion of a shoe just below the rand-crease, contact ot the gacinf: element at this point furnishiup` the most accurate location oli the nail with` respect to the crease, That is, by determining' tlu` point oli insertion oll the liasteninp; by measuring' its distance trom the point at which it is desired it Ishall closely approach`r this relation is obtainable without danger ol1 the 'fastening penetratingl the exposed portion olf the shoe.

Vere it lett tor the countr'-a1"a oft the shoe-upper to position the sections by its pressure against the ends ot the projections 5t? as the ja el; is moved into nailing position, the rulgibingv ot the upper-material over the projections would be liable to mutilate it. To avoid injury to the stock` the rage-pro jections are allowed to contact with the work oni;Iv after it is beneath the die-block. Attached to each section is a wire or other 'flexible member 60 running' over a sheave (S2 rotatably inointed upon Vthe plate 'll. From the sheave, each wire hangs parallel to the side rods` and opposite groups ot these wires carry a rod G4 movable in a bracket 66 depending' from the traine. The lower end ot each rod is weighted at 68 the magnitude ot' the total weight of this portion ot the system being sufiicicnt to overcome the expanllll (ill

sive torce ofthe springs 50,L so that the sections 215 are held bachi with the springs compressed and out oft the path of the shoe as the ack lo is carried into nailiiigf position. Each weight titl may be further guided and prevented against rotating about the axis o'" the rod (ifi by n curved portion Tt) partially enil'n'acing the ladjacent side rod. Formed upon the under side ot each weight is a downwardly and rearwardly `inclined surface T2, with which may contact an opposite'ly inclined surta-,ce T-i `upon a bracket T6 secured to om` side ot' the base ot' the jack. lilith the jack d awn ont inthe position to receive a shoe. the surface 742 separated trom 72. allowing the weight. 78- to exert its otl'cct 'to hold the nail-inserting sections 28 out and the gaging projections 56 clear oi' the counter oi' the shoe when the jack is thrust in. Upon this jnstsnientioned movenient, the surface 7l contacts with 72, elevating 'the weight and relieving the springs 5t) troni its ett'ect, so that said springs act. to carry the sections 2S toward each other, causing the projections 56 to contact with the counter of the shoe, which at this time has reached its position beneath the dieblock and is at rest. Direct contact with the end ot the inl'oj'ections, without 'rubbing action, is thus had, and the ends of the nailholding passages 32 are presented in the fde sii-ed relation to the heel-seat. Any excess ot' movement oft' the rod 434i, under the Iinfluence of the surfaces .7 2 and '74, over that ot the gage-projections is compensated for by springs 77 included in the flexible menibcrs 60, These springs, naturally elongated under the tension of the weights, contract as the projections are moved in bythe springs 52, and thus 'take up any looseness in vthe members G0.

The top girt 2t) carries, upon 'its under face, an extension 78. from which depends a series oi narrow walls 80 arranged to register with the sl'iacesbetween the walls 48. so that when the top girt is lowered 'by the side rods, leach wall 80 will 'strike the upper end ot a bar to depress it against its spring i6 and drive the nail in the passage 32. 'On account of the inclination ot the driver-bars 42, 'their upper ends, as they descend, are shifted inwardly toward :the center ot the die-lilock- Contact, however', between the barsand the actuating elements 'is maintained by the extension ot the walls 8() between the abutment-walls 48, there being provided a surface continually contacting with the bar during its entire 'downward travel. It will loe seen that by having `the drivers move with the nail-holding sections, and the comparatively massive walls'80 1having their operating' `movement and producing their effect upon the drivers independently. oit thetravel ofthe sections, and thus unaffected by their positions, the locating oi' all the ,elements of the inserting mechanisms may ibe lacc'oniplished rear-lily, and without throwing harmful strains upon relative-ly trail' parts, .may be the case with the drivers ot the macliine oi the previouslymentioned application.

Viren nails are driven into the hoel-seat with an inward inclination, there is a coinponent of the driving force which acts against the springs 50, tending to 'separate the sections 28 troni the work. To guard aga-inst this, the top girt and its extension 78 contain a verticalpassage 8st lying above each of the o'verhanging portions 3() of the sections. -lln each passage 811% operates a retaining member', 'furnished by Aa plunger or contact-rod 86, forced down by a spring 88 toward the wall A screw 90 `i's threaded horizontally `into each plunger, and operates in a vertical slot 92 in the top-girtexf tension. This limits the downward ino-ve nient ot' the plunger under the influence ol" its spring, so that its lower extremity, when the top-girt is raised, is out ot' contact with the portion 30 of the corresponding inserting-section. Vhen, however, the top girt descends and the nails are driven by the aci tion-of the walls 80 upon the driver-bars 42, the plungers 86, before'the drivers contact with lthe nails in the passages 32, press upon the `portions 30, and thus irictionally retain lthe sections against outward displacement tunder the driving pressure.

To .state briefly the general operation of the machine, it maybe said that with the jack 16 drawn out, the operator places a shoe S upon it, and pushes the jack in until the heel-seat 'of 1the shoe -is vertically alined with the recess lll. Until the slice `has reached this position, the gaging projections 5G :are maintained' away vfrom it by the weights 68. fBut when these weights are raised by the jack-surfaces 74, the springs act to carry the sections 28 inwardly, the con tact ot' "the projections with the coimterportion ofthe shoe near fthe rand--crease correctly locating the `ends of the passages 32 over the heel-seat. Now the machine is started in operation, and upon movement oftI thctop girt, thedistributor 38 is tripped, so that it delivers Va charge of Vnails 'N vtln-'ough the tubes 36 and passages 34 into the holding passages v32. =In this descent of the top girt, the sections are locked by the trictional engagement ot' the plungers 86, and then the lactuating `walls 480 strike the Vends of thedriver-bars 42, so that the drivers 40 are lforced down against the nail-heads, inserting the nails in the heel-seat. Upon reverse movement of the top girt, Athe retaining pressure ot 'the plunger 86 is removed `from the inserting sections, xand the walls 8O are carried out of contact with the driver-bars. As soon as ythe outward travel foi' zthe jack is initiated, the `weights llt) G8 are released, so that the oree of the springs 52 is again etl'ective, and the gaging projections 56 removed from the shoe, their movement ot' withdrawal with the sections continuing without contact with the upper.
